    Abstract
  • In order to roundly optimize the scale, structure and layout of port cluster system, improve their dynamic harmony, a double planning model was built by using multi-agent simulation method based on complex system theory, and a multi-agent(MA) genetic algorithm(GA) was proposed. Global optimization agent was established to achieve the synergic optimization among the agents of port cluster system, the scale effect factor of port was introduced, an allocation model of freight volume in the hinterland of port was constructed and applied in the switching rules of port agents. Computation result shows that the model tends to the optimal solution after the 60th iteration, the total benefit of the system increases by 48%, its structure and size become rational, so the model and algorithm are feasible.
